杨树抗云斑天牛系列新品种是中国林科院林研所通过杂交和选择培育出来的良种。经５年生和２年生引种试验林数据分析结果表明：不同无性系间在树高和胸径两性状上存在显著差异，树高的广义遗传力高于胸径的广义遗传力，胸径的变异系数高于树高的变异系数，胸径的遗传变异较大（变异系数大于１０％），抗云斑天牛系列新品种（３４－１７，３４－１３５，３４－３１４，３４－３０１，３４－２８６，３４－２９７和３７－３３）生长优于当地主栽品种Ⅰ－６９杨，３４－１８８杨的生长接近Ⅰ－６９杨。
Poplar anti-Yun Tianniu series of new varieties of Chinese Academy of Forestry Lin Institute through breeding and selection of cultivated elite. The data of 5-year-old and 2-year-old pilot plantations showed that there were significant differences in tree height and DBH between different clones. The general heritability of tree height was higher than that of DBH, and the variation coefficient of DBH was higher than The coefficient of variation of tree height and the variation of DBH were large (the coefficient of variation was more than 10%), and the new varieties -297 and 37-33) grew better than that of the native cultivar I-69. The growth of 34-188 was close to that of Ⅰ-69.
